Wow these tracks sound professional! It is also impressive how much you completed for a jam at this quality.
Rootmother's Reverie: this is a vibe! The instrumentation selections feels spot on and layered in a way that feels ethereal. The voice parts in particular feel mix in with lovely sound staging. Even when you give a hint of a dissonant harmony half way through I still feel I am in a safe place and making progresses in a place I want to say in forever. I really appreciate the build up in intensity and then a return to the intro, that moment of rest feels so light and well earned.
Slay the Rot: The rhythmic drive traversing through different harmonies go from danger, to turning the tides, and then to feeling like the danger is greater than we original thought. The mix felt a touch muddy on one of my headphones (Fiio ft5) but gave another listen on Sennheiser HD600 and things were much more clear, so I think that is more on my end of the equipment I am using. I don't know if it is worth another listen on you end on different devices and see what you get? It is a busy track and everything feels weighted just right. I like how it sounds like a single violin coming in through the frantic choir and then takes over into getting its own backing instruments, sounded great!
Intermezzo in a Twilight Grove: I am catching that non functional harmony chord alternating pattern Blue Lava mentioned from Chrono Trigger. I remember trying to write something similar as an exercise once but couldn't come up with anything original. This sounds very much like your own, I think I might have missed that reference to Chrono Trigger if didn't read the comments. Like a mix of Chrono Trigger and the voice parts sounding in the same genre as the outros to Outlaw Star. I really appreciate the harmonic progression at about the 3/4 mark of the track. I felt like the piano sustain and the voice sustain were fighting for some space at times in the first half. I don't know if that would be worth checking again to see if that would tighten up the mix a bit. I am not trying to downplay how great I think this track is. Really just a curious suggestion on my part. The bells have the right amount of attack and reverb though! It really help compliment the vibe instead of cutting through everything as bells have the power to do. I think I really just wish the track was longer cause I enjoy it so much!
Rotmother's Requiem: I can definitely feel a powerlessness against the forces of nature. That hard stop into the music box sounding instrument and then a build back into every more danger than before feels real! It sounds like the strings from there are backed by horns which helps them shine through when they sounded like they were fighting for a voice before, a great contrast between sections! Ending with the music box instrument sounds like a tragic defeat took place! All these tracks took me on what felt like a an emotional journey that was very well crafted and intended. Thanks for sharing!
